-GAS-BIURVNER. f

Be it known'that I, -WILLiAM P. ,WIEMANN,

, a resident of Allegheny, in the county of Allegheny-and State ofPennsylvania, have in-" vented acnew and useful Improvement in followingto bea full, clear, and exact dc- Gas- Burners; and :I do hereby declarethe scription thereof. I

My invent on relates to gas-burners," and has speclal reference togas-burners for use 1n connection withboilers, furnaces, kilns,'&c".;

and the 'object of the invention is to; rovide. a cheap,- simple,effective,-and reliab eform of such burner.

In the accompanying drawings, Figure 1 a longitudinal central section'of the burner,

and Fig. 2 is anenlarged cross-sectionof' the same on the line II IIof.Fig.1. Y

As illustrated in thedrawings,1' is a casing for formingamixing-chamber. 2 whichv is from the outer; casin 1 "by a connection18', which" is provided "with a a tion 9 extending into'the gas-chamber5' and having a close 9, and extending through an opening in this ortiong, which ro passes 1 at the outer end with an adjusting-wheel15.

This valve 13 is adapted to be adjusted within the outwardly-flaring end4" of the casing I 44 to form the burner-opening. The valve 13 issecuredto the rod- 12 by nuts 13 13".
